UART/Serial Port Emulation over BLE seems not running

[AugROS]

Hello guys,

I've a PCA10040 connected to my laptop.

It works fine with all the .hex BLE template example in the nordic SDK except with the UART example.

After download the ble_app_uart_pca10040_s132.hex I expected the device is advertising with the device name "Nordic_UART" and LED 1 is blinking (period 2 sec, duty cycle: 10%).

I also started Putty Emu Terminal 

Nothing happen!

The LED1 on the PCA  is stady ON.

Any idea or suggestions?

Of course as said earlier, the other BLE example as ble_app_template_pca10040_s132.hex   works fine.

Hi Amanda,

thanks for your reply.

I erased the PCA10040 then download again the UART .hex file.

The LED1 and LED2 are steady ON. No flashing as 

No adversting on my mobile app as expected. (#define DEVICE_NAME                     "Nordic_UART"    )

Where I'm doing wrong?

The documentation here is still valid for UART over BLE handling?

Hi Augusto,

How do you download the image? via nRF Connect programmer, nRF-Command-Line-Tools or Segger?

Is the image from nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral\ble_app_uart\hex or generated by you? Is it an unmodified example? If not, what do you modify? 

Are you able to do the following test?

Please download nRF-Command-Line-Tools and use the image ble_app_uart_pca10040_s132.hex under nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral\ble_app_uart\hex

Execute the following commands in the Command Prompt(CMD):

nrfjprog -eraseall

nrfjprog --program ble_app_uart_pca10040_s132.hex --sectorerase --verify -r

Do you see "UART started." with the terminal tool? If not, you could press the reset button and check again. It should adverse as "Nordic_UART" now. 

Please let me know this can help or not. Thanks.
